Secure, Fast, and Energy-Saving Consensus Mechanism with Legal Identity

The main purpose of consensus is to collaborate all decentralized nodes to work
together with the same running program and the same updating database. Many
public blockchain systems, associated with public nodes, are currently raising the
issue of high energy consumption within their total community, racing for producing a
new data block. Some blockchain systems may avoid this issue by limiting the certain
number of their nodes, to produce and validate a new data block.

Angelchain, caring about energy consumption and global warming whilst
believing in true decentralization with public participation, has allowed the
certified nodes with legal identity to participate in the consensus mechanism by taking
turns to produce and validate a new data block.

A new certified node will be added, associated with an algorithm for forming a set of
100 nodes, into the list of a group. Each group will be automatically and publically
allocated, in the queue, to the sequence of 100 coming data blocks. The current
situation of a node being disqualified is taking into account of the algorithm.

With this mechanism, it prevents all nodes, over the world, to do the redundant
work of producing a new data block. Moreover, it is more difficult for a malicious
user to insert its fault data block into the system since the block stores the node ID
of its producer. The node ID of the producer must be a qualified node with legal identity
and within the announced assignment of the data block production. Therefore, all
nodes in the community can easily validate a new coming data block, associated
with the node ID stored within, before recording it into its database system. We
name this consensus mechanism Queued Proof of Stake or QPoS.
